I have always used a hair dryer to get off stickers. I was the one as a kid that stuck them everywhere so my dad showed me how to do it and it was my job to clean up my messes. The glue on the back warms and becomes sticky again. You can slowly pull it off or while you are pulling if it gets to hard to use the blow dryer while pulling it off. Afterwards I use either an orange cleaner or goof-off to get the last residue off. Good Luck!
